Yes (64)


Blast resistance










Catches fire from lava


Ancient debris is a rare ore found in the Nether, and is the main source of netherite scraps. Its high blast resistance makes it immune to normal explosions. In item form, it floats on lava and cannot be burned by any form of fire.


Natural generation

Ancient debris spawn rate per layer; Y=15 has the most ancient debris. Average only.

Ancient debris generates in the Nether in the form of blobs. Up to two blobs may generate per chunk: one blob of 1–3 ancient debris attempts to generate with a periodic normal distribution (similarly to lapis lazuli ore) from levels 8 to 22, and an additional blob of 0–2 ancient debris attempts to generate randomly from levels 8 to 119. On average, Y-level 15 has the most ancient debris.

There is an average of 1.65 ancient debris blocks per chunk[needs testing], with a normal maximum of 5. However, it is technically possible for up to 11 ancient debris to be found in a single chunk; adjacent chunks can generate blobs on the border with up to 2 blocks spawning in an adjacent chunk. As of Java Edition 1.16.5, on average they generate 1.56 ores per chunk. Given this number, and that there are 32768 blocks in a chunk (16 * 128 * 16), there is approximately a 0.004% chance that any randomly selected block will be an ancient debris block.

Ancient debris never generates naturally exposed to air and can replace only netherrack, basalt, and blackstone.[note 1] It may also generate alongside smaller pockets of lava.


Ancient debris drops itself if mined by a diamond or netherite pickaxe. If mined by any other tool, it drops nothing.

Issues relating to "Ancient Debris" are maintained on the bug tracker. Report issues there.


  • Despite ancient debris' rarity, emerald ore is actually rarer; emerald ore has a lower spawn chance per chunk, and while ancient debris can appear in blobs as large as five in any Nether biome, emerald ore generates only as individual ore blocks in mountain biomes.
  • The texture of the ancient debris is supposed to look like pressed metal plates.[1]
  • Ancient debris is actually what remains of the mining activity of the piglins, who extracted all the original netherite ore.[2]
  • It is possible to find blobs of up to 20 contiguous ancient debris - up to five debris can generate in a chunk, so if a blob of five generates in adjacent corners of four different chunks, a blob of 20 debris would be created.
  • Despite having the same blast resistance as obsidian, ancient debris can be moved by pistons.

  1. The generation system explicitly attempts to place ancient debris where it is not exposed to air. Rarely, ancient debris can be exposed by later generation processes. It can also be exposed to fungi.
